Furthermore, instrument can't be renamed. If possible, please make it work.
I have over 40 instruments in data manager. If I delete data folder, they would be all gone.
The problem is NOT about data, it's about instruments.
Currently no way to export or backup instruments or data in SQX.
Allow remote access(main menu->Remote access) without password protection and then call the link below from your default web browser
http://localhost:8080/instruments/removeInstrument?instruments=
There is no way how to delete or rename empty instrument.
You can delete your data folder \user\data and then reimport the data.
